The measure would have barred supervisors from holding another job, similar to the prohibition in place for other elected officials, including the mayor. It was aimed squarely at Supervisor Mark Farrell, the only member of the board who currently holds down two jobs. The moderate, pro-business supervisor from District Two makes $108,000 a year in his elected role and also earns more than $100,000 a year as a managing director at venture capital firm Thayer Ventures.

Jon Golinger, the former president of the Telegraph Hill Dwellers neighborhood association who was the main force behind the proposed ballot measure, had been trying to collect enough signatures to qualify it for the June ballot.

Now that plan is on hold for two reasons, Golinger said. One is to expand the measure to encompass a package of ethics reforms, including possibly tightening requirements on who must register as a lobbyist in the city and closing a loophole that allows interest groups to circumvent a ban on gifts to officials of more than $440 a year from a single source.

The other reason is Golinger is working on the signature gathering effort to qualify separate ballot measure that would require voter approval for any waterfront development that exceeds current height limits.

“It was a practical decision,” Golinger said of shelving his moonlighting proposal. “We decided to postpone” until either November or 2015.

Limited-growth and environmental advocates from the city’s left, who in November went to the ballot to defeat a planned luxury condominium development near the Ferry Building known as 8 Washington, are now pushing to get the height limit proposal before voters in June.

“We want June for a number of reasons,” Golinger said. “The main reason is to carry the energy and momentum from the last election. … It’s really the second chapter of that story that we’re telling here.”
